Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596942, here are decompositions:

19 + 31596923 = 31596942
29 + 31596913 = 31596942
43 + 31596899 = 31596942
53 + 31596889 = 31596942
59 + 31596883 = 31596942
61 + 31596881 = 31596942
103 + 31596839 = 31596942
149 + 31596793 = 31596942

Showing the first eight; more decompositions exist.
